To all whom it may concern. z

Be it known that I, JOHN S. BRENNAN, al citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of' Wisconsin, haveinvented certain new and useful Improvements in Convertible Fluid-Fuel 'Kindlers' and Heaters for Stoves; and I do herebydeclare that 'the following is a full, clear, and exact description thereof.

This invention relates to new and useful' vimprovements in stoves, particularly of that type which are'adapted to utilize both solid and fluid fuel.

It is the primary object of the invention to provide a means whereby the usual water container in the fire box mayA be heated either by solid fuel on the grate, or by vfluid fuel, or ifdesired by both solid and fluid fuel to supply a great amount of heat to the said container for meeting unusual condi` tions of use of thehot -water system associated therewith and to provide for van eX- ceedingly rapid heating of such water.

It is further an object to utilize the fluid fuel heating means as a means forrkindling solid fuel such as coal ini the fire box of a stove whereby the starting of a fire is greatly facilitated and whereby the annoyv` ance of the usual laborious method of kindling is obviated. f

A still further object resides in the provi'- sion of a single burner member which is movableto direct its flame either toward the grate member of the fire box to kindle the solid fuel thereon, or toward the water container to heat it when there is not a solid fuel. re in the stove, whereby the fullest heating power of the burner may be utilized. in either of the operations.

Tit-h the above and other objects and advantages in view, the invention resides more particularly in the novel combination, arrangement and formation of parts more particularly hereinafter.described and particularly pointed out in the appended claims.

Reference is had to the accompanying drawings whe-ein similar characters of reference designate. corresponding parts throughout the several views and in which:

Figure 1 is a vertical sectional View through-'the fire box of a stove equipped with the present invention, the sectional view being takenon the line 1-1 of Fig. 2.

A Fig. 2 is a horizontal sectional view talren 55 through the lire box 1n a plane including the axis of the burner member, this view being on the line 2--2 of Fig. 1.

Fig. 3 is a vertical sectional View taken transversely through a fire box on the line 3-3 of Fig. 4, and illustrating a modified form of burner andwater container.

Fig. 4 is a horizontal sectional view takenm through a fire-box on the line '4f-4 of Fig. 3.

Fig. 5 is a detail sectional view on the line 65 5-5 of Fig. Il showing the operating and indicating means' of the burner.

eferring now more particularly to Figs. 1 and 2 of the accompanying drawings,

there is' shown the fire box portion of a 70 stove including the outer side wall 5 which -is the outer wall of the stove, and the inner Y wall 6, the front wall of the stove and of the fire box being designated at' 7. Disposed adjacent thewalls 5 and 6 are the 75 usual grid members 8 which are inclined V away from the walls toward their bottoms and below which is positioned the grate 9. Lying against the inner faceof the grid member adjacent the wall 5 is a water con- 80 'tainer which includes series of plpes 10 which extend horizontally and form what 1s termed the water container and which are connected 1n any suitable manner to a water heating system, not shown, these pipes being adapted to be normally heated Abya coal or other solid fuel lire disposed on the-grate 9. The kindling and water heating burner comprises a pipe section 11 rotatably mounted in a bearing 11', provided on the rear 90 portion of the inner face of the wall 5 and in a bearing 12 carried by the wall 7 through which the pipe is passed, whereby the burner member extends horizontally between the grate 9 andthe pipes 10 and may be rotated v95 to direct the flames issuing from 'a longitudinal series of jet openings 12 in' its side,

either Atoward the grate 9 or toward the water pipes 10. The rear end of the burner.

pipe is suitablyclosed, and the front end .which projects outwardly of the stove wall 7 carries an air mixing member 14 with which is connected in the usual loose manner, the valved branch 15 of a suitable supply pipe For rotating the burner pipe to either of its operative positions, an arm 16 extends laterally from its forward portion and is passed through a vertical slot 17 in the side wall 5, the free end of the arm being directed laterally and provided with a transverse head 18, substantially square in cross section. The slot 17 is of `length that abutment of the arm 16 against either end thereof, determines the proper position of the burner for its respective operation, and the position of the slot and arm is vsuch relatively, thatv at either limit of 'movement of the arm, one of the flat faces of the head y 18 is disposed substantial-ly .in a horizontal plane, and these faces 'carry symbols 19,

which indicate the operative position of the burner whereby a person looking down-` wardl'y on the head will be appraised of the loperative position of the burner.

Taking up now. the modified structure shown in Figs. 3 to 5 of. the drawings, there is shown a conventional irebox structure similar to the one heretofore described and wherein as in the i revious structure 5 designates the outer si e wall,'6 the inner' side wall, 7 the front Wall, and 9 the/grate. Adjacent the inner side Wall 6 is the usual grate member 8, but adjacent the wall 5 is a tank member 8a forming the Water container,

to thus dispense with the pipes 10 of the previous structure. The bottom of this member 8a, however, comprises a plurality.

of grid sections 8b, the upper being in the shape of a tank. A, v

The burner member of the present strucportion only ture comprises a pipe 20disposed longitudinally in the re box between the member 8" and the wall 5, and above the grate S). The end of the pipe adjacent, the back of the stove is closed by a cap '21 andv is journaled in a bearing 22 carried by the adjacent portion of the wall 5, and the 'front end of the pipe is extended outwardly ot the stove through a bearing sleeve 22 carried in the' front wall 7 and carries the usual air mixing member 23 with which is connected in the usual loose manner a valved supply pipe 24.. The pipe isprovided with spaced longitudinal slits E25 through which the gas escapes and is ignited in two sheets oi flame 'which are adapted to lie at the sides of and envelop either the water container or the grate according to whichever (.hrection the 4pipe is turned as indicated in Fig. lVhen the pipe is turned 'for kindlingi'luel on the grate, it is noted that one sheet of llame will directly engage with the vfuel and the other sheet will pass under the grate and will. engage with the Fuel at a point more. remote. For actuating the burner pipe to either dc-l sired position, and for indicating the posi- 65 tion' of the pipe, the bearing sleeve 22 is provided on the outer face of the front wall 7 with a flange 26 which has its upper portion enlarged to form asymbol plate and carrying `the symbols 27. A ring 28 is4l clamped on the pipe outwardly ofthe flange 26 and this rin grate members 8, it does not in'any manner,

interfere with the fire chamber, At the 'same time the burner is fully protected from thev solid fuel fire due-to its location, hence it cannot be damaged byv're for clogged by ashes'- v l Iolalrn: I v 1.' In a re boXineluding .a grate, a side grid member and a .Water container associated with the grid 'membenthe' combination i or' a fluid fuel burner apparatus permanentlysecured in the/fire box ljuxtaposing'the grid member, said apparatus" being `shiftable to adapt it for either kindling fuel on the grate' or for heating water .in the container.
